This application claims the benefit of priority to U.S. ProvisionalPatent Application Ser. No. 63/155,915, filed on Mar. 3, 2021, thecontents of which are incorporated in this application by reference.

FIELD OF THE INVENTION

The present invention relates generally to suspended ceiling systems andmore particularly to a pocket and adjustable trim piece that isremovably attached and can be easily adjusted up or down, or removed andreplaced with an entirely new piece, without the need to remove anyother elements of the suspended ceiling system.

BACKGROUND

Some ceiling systems include a grid support system hung from an overheadstructure (i.e., a suspended ceiling system) which includes an array oforthogonally intersecting longitudinal grid support members and lateralgrid support members arranged in a fairly uniform pattern with regularintervals. The longitudinal grid support members and the lateral gridsupport members define a plurality of grid openings configured tosupport individual ceiling panels. Mechanical and electrical utilities(such as wiring, plumbing, etc.) may be conveniently routed in a hiddenmanner in the cavity or plenum formed above the grid support members andceiling panels, making suspended ceiling systems a practical and popularceiling option for residential, commercial, and industrial buildingspaces.

Certain suspended grid ceiling designs call for a consistent visuallooking from the outside. This includes the visual of shades inside thecommercial space.

Traditionally, such finishing is completed with studs and drywallmaterials, as the architect details this part of the building withlittle planning or thought to how the trim is installed or whether thetrim can be easily removed, without removing the entire suspendedceiling structure. Indeed, as tenants in commercial spaces turn over, itis desirable to update the space's look by updating the finishcomponents such as trim around the islands or edges of the suspendedceiling, without changing the visual looking into the building. Becauseconstruction and deconstruction is redundant, expensive, and wasteful,having a perimeter pocket fixed to the ceiling is undesirable. However,the connection rigidity provided by fasteners is desirable.Specifically, the trim piece should not rotate or droop once it isattached.

To provide for additional ornamental designs, it is also desirable thatthe trim pieces be adjustable in a direction substantially perpendicularto the ceiling. For example, the system should be capable ofaccommodating a number of trim pieces with bevels at different anglesfrom the plane of the ceiling.

Accordingly, there is a need for ceiling system to which trim pieces maybe rigidly and removably attached and thereby easily removed without theneed to remove additional elements of the ceiling perimeter structureand where the vertical height of the trim pieces can be easily adjustedto provide for more ornamental ceiling designs.

SUMMARY

According to an embodiment of the invention, an adjustable trim systemfor a suspended ceiling is disclosed. The trim system includes a pocketthat attaches to the perimeter of the suspended ceiling. The pocket hasa top portion attached to a first leg and a second leg on opposite endsof the top portion. The first leg and the second leg extending downwardfrom the top portion with each leg having an exterior surface and aterminal edge. At least one pocket hook projects outward from theexterior surface of the second leg towards the top portion with one ofthe pocket hooks projecting outward from the terminal edge of the secondleg. In addition, the first leg is longer than the second leg. Thepocket is removably attached to a trim piece that is made of a stemsection having a top end and a bottom end between which the stem has anengagement surface and opposite side surface. A trim section projectsfrom the bottom end of the stem. At least one trim hooks and optionallya stabilizer bar project outward from the engagement surface. The trimhooks project in the direction of the bottom end and are located closerto the top end than the stabilizer bar. Each of the pocket hooks and thetrim hooks include a projection portion connected to an attachmentportion with a termination end opposite the connection to the projectionportion.

In certain embodiments, the trim system includes a spacer locatedbetween the top of the stabilizer bar and the terminal edge of thesecond leg or the bottom of the pocket hook projecting out from theterminal edge of the second leg. The space can be made of a materialselected from a group consisting of polymers, rubber, or a mixturethereof. Furthermore, the top of the stabilizer bar, the terminal edgeof the second leg, or the bottom of the pocket hook projecting out fromthe terminal edge of the second leg may be textured to better hold thegasket or spacer.

In certain embodiments, the thickness of the termination end of thepocket hooks does not exceed 0.1 inches. Indeed, the attachment portionmay taper to that thickness and the taper may be continuous or include acurve.

In other embodiments, the trim piece contains 6 trim hooks and 5stabilizer bars spaced a substantially equal distance apart. Forexample, the distance may be about 1 inch (e.g., 1.0 inches plus orminus 0.07 inches).

In certain embodiments, the trim piece includes a flange projectingoutward from the bottom edge of the trim piece. One or more flanges mayalso project out from the exterior surfaces of the first leg or the topportion of the pocket. When two or more flanges project from the topportion of the pocket the flanges closer to the first leg projectfurther than the flanges farther from the first leg.

In certain embodiments, both the trim hook terminal edge and pocket hookterminal edge have a thickness from 0.13 inches to 0.27 inches.

In certain embodiments, the opposite side surface of the trim pieceincludes a notch closer to the bottom edge than the location on theengagement surface closest to the bottom edge from which the trim hookprojection portion projects outwards. In such embodiments, the notch maybe about 0.365 inches (e.g., 0.365 inches plus or minus 0.07 inches)closer to the bottom edge than the location on the engagement surfaceclosest to the bottom edge from which the trim hook projection portionprojects outwards.

In certain embodiments, on the trim piece, the location from which thetrim hook projection portion projects out from the engagement surfacewhich is closest to the bottom edge (i.e., the bottom of the projectionsurface that is closest to the bottom edge) is at least about 3.77inches (e.g., 3.77 inches plus or minus 0.07 inches) from the bottom ofthe trim section.

In certain embodiments, the opposite side of the trim piece includes atleast two ribs, wherein a first rib is closer to the top edge than asecond rib and the first rib projects outwards from the opposite sideand downwards towards the bottom edge and the second rib projectsoutward from the opposite side and upwards towards the top edge. Thesetwo ribs form a channel. In other embodiments, the opposite side of thetrim piece may include two or more channels. For example the oppositeside may include at least four ribs forming two channels, wherein afirst channel is closer to the top edge than the second channel, thefirst channel formed by a first rib closer to the top edge than a secondrib and the first rib projects outwards from the opposite side anddownwards towards the bottom edge and the second rib projects outwardfrom the opposite side and upwards towards the top edge, the secondchannel formed by a third rib closer to the top edge than a fourth riband the third rib projects outwards from the opposite side and downwardstowards the bottom edge and the fourth rib projects outward from theopposite side and upwards towards the top edge.
